BACKGROUND OF THE INVENTION

The present invention relates generally to crowdsourcing of meetings, and more particularly to the crowdsourcing of meeting topics.

Natural language processing (NLP) is a field of computer science, artificial intelligence, and linguistics concerned with the interactions between computers and human (natural) languages. As such, NLP is related to the area of human-computer interaction. Many challenges in NLP involve natural language understanding, that is, enabling computers to derive meaning from human or natural language input, and others involve natural language generation.

In NLP, latent Dirichlet allocation (LDA) is a generative model that allows sets of observations to be explained by unobserved groups that explain why some parts of the data are similar. For example, if observations are words collected into documents, LDA posits that each document is a mixture of a small number of topics and that each word's creation is attributable to one of the document's topics.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention provide the capability of notifying participants of the meeting that another meeting is discussing a similar topic and that the other meeting has more productive use and a better understanding of the topic being discussed.

Implementation of embodiments of the invention may take a variety of forms, and exemplary implementation details are discussed subsequently with reference to the Figures.

FIG. 1 is a functional block diagram illustrating a distributed data processing environment, generally designated 100, in accordance with one embodiment of the present invention. FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made by those skilled in the art without departing from the scope of the invention as recited by the claims.

Distributed data processing environment 100 includes server 102, client devices 104 and 106, all interconnected over network 108. Network 108 represents, for example, a telecommunications network, a local area network (LAN), a wide area network (WAN), such as the Internet, or a combination of the three, and includes wired, wireless, and/or fiber optic connections. Network 108 includes one or more wired and/or wireless networks that are capable of receiving and transmitting data, voice, and/or video signals, including multimedia signals that include voice, data, and video information.

In the depicted environment, server 102 is one or more of a management server, a web server, or any other electronic device or computing system capable of receiving and sending data. In other embodiments, server 102 represents a server computing system utilizing multiple computers as a server system, such as in a cloud computing environment. In some embodiments, sever 102 can be represented as a node such as cloud computing node 410. In another embodiment, server 102 represents a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of communicating with client device 104 and client device 106 via network 108. In another embodiment, server 102 represents a computing system utilizing clustered computers and components to act as a single pool of seamless resources. Server 102 includes meeting program 120 and database 130.

In the depicted embodiment, database 130 resides on server 102. In another embodiment, database 130 may reside elsewhere in distributed data processing environment 100, independently as a standalone database that is capable of communicating with server 102 via network 108. Database 130 may also reside on a client computing device, such as client devices 104 or 106. A database is an organized collection of data. Database 130 is implemented with any type of storage device capable of storing data that is accessed and utilized by server 102, such as a database server, a hard disk drive, or a flash memory. In other embodiments, database 130 represents multiple storage devices within server 102. Database 130 stores information, such as company personnel directories, calendar entries, meeting logs, meeting descriptions, presentations, personnel locations and phone numbers, meeting summaries, etc.

In the depicted embodiment, client devices 104 and 106 are one or more of a desktop computer, a laptop computer, a tablet computer, a specialized computer server, a smart phone, or any programmable electronic device capable of communicating with server 102, and another client device via network 108 and with various components and devices within distributed data processing environment 100. In general, client devices 104 and 106 represent any programmable electronic device or combination of programmable electronic devices capable of executing machine readable program instructions and communicating with other computing devices via a network, such as network 108. In an embodiment, client devices 104 and 106 each send a data stream which may comprise one or more of audio, video, digital presentation material, facial expressions, text, etc. to server 102 via network 108. In an example, client devices 104 and 106 are hosting separate meetings and sending separate live data streams to server 102 via network 108. In various examples, client devices 104 and 106 may each have teleconferencing software, video chat software, scanning software, etc. that enable client devices 104 and 106 to collect and send the data stream to server 102 via network 108.

In depicted distributed data processing environment 100, meeting program 120 resides on server 102 and identifies similar data streams from one or more client devices and determines if one data stream might be of use to participants of a meeting that created a second data stream or vice versa. In one embodiment, meeting program 120 receives a real time data stream of a first meeting from a first client device and determines the topics of discussion. Meeting program 120 also receives a real time data stream of a second meeting from a second client device and determines the topics of discussion. Meeting program 120 assigns a value based on the productive use and understanding participants of the meeting have of a topic being discussed in the meeting. Meeting program 120 then determines if the topics of discussion are similar for the first and second data streams and if it would be helpful to link the two meetings because one group may understand a topic while the other group does not understand the same topic.

In one embodiment of the present invention, meeting program 120 can make this determination by using latent Dirichlet allocation (LDA). LDA is a generative model that allows sets of observations to be explained by unobserved groups that explain why some parts of the data are similar. In an example, if observations are words collected into documents, LDA posits that each document is a mixture of a small number of topics and that each word's creation is attributable to one of the document's topics. In one example, meeting program 120 determines that the participants of the meetings should be joined because a threshold of polarity of productive use and understanding for the topics that are similar has been reached. Productive use and understanding is the determination meeting program 120 makes of the participant's mental grasp of a topic being discussed. For example, if the participants of a meeting were novices in a topic meeting program 120 may determine that the participants have a low productive use and understanding of the topic. Conversely, if the participants of the meeting are experts in a topic meeting program 120 may determine that the participants have a high productive use and understanding of the topic. Meeting program 120 sends an invite to both client devices to link the meetings.

In another embodiment, meeting program 120 can make this determination by using latent semantic analysis. Latent semantic analysis (LSA) is a technique in natural language processing, in particular in vectorial semantics, of analyzing relationships between a set of documents and the terms they contain by producing a set of concepts related to the documents and terms. In another embodiment, meeting program 120 can make the determination by using latent semantic indexing. Latent semantic indexing (LSI) is an indexing and retrieval method that uses a mathematical technique called singular value decomposition (SVD) to identify patterns in the relationships between the terms and concepts contained in an unstructured collection of text.

In another embodiment, meeting program 120 may identify similar topics using natural language processing and deem that the meetings are similar and therefore meeting program 120 will send an invite to both client devices based on the similarity alone. In one embodiment, one data stream or meeting topic may have happened previously, but meeting program 120 still determines if there is a match with the live data stream. In yet another embodiment, meeting program 120 determines there is a match after the two data streams are no longer live and sends a copy of the transcript or summary of the meeting to personnel involved in each meeting. In yet another embodiment, meeting program 120 is located on multiple client devices and operates in a peer to peer mode. Meeting program 120 is depicted and described in further detail with respect to FIG. 2.

FIG. 2 is a flowchart depicting operational steps of program 200, which is a function of meeting program 120, in accordance with an embodiment of the present invention. Meeting program 120 operates on server 102 and is used to identify similar data streams and determine if one data stream might be of use to the participants of a meeting that created a second data stream or vice versa. In one embodiment, meeting program 120 monitors multiple data streams and determines the similarity of the data being discussed as well as the productive use and understanding the creators of the data stream have of the topics being discussed. In one embodiment, meeting program 120 initiates in response to receiving a data stream from a client device. In another embodiment, meeting program 120 constantly monitors multiple client devices in an enterprise environment and begins the operational steps of FIG. 2 when server 102 receives a new data stream from a client device (e.g., client device 104).

Meeting program 120 receives data from a client device (step 202). In one embodiment, meeting program 120 receives data from client device 104, via network 108. In an example, client device 104 is located in a conference room for a meeting. Client device 104 has a microphone to gather audio data, one or more cameras to gather video of the participants of the meeting, various sensors that may record heat signatures or shifting in seats, gaze tracking devices, or any other data sources known by someone skilled in the art. Client device 104 may also scan documents that are presented during the meeting. In this example, client device 104 continuously sends the data from the meeting to server 102 and meeting program 120 in real time. In one embodiment, meeting program 120 may receive data from multiple client devices that are collecting data from a singular meeting and sending the collected data to meeting program 120. In an example, the multiple client devices, such as client device 104 and other client devices (not depicted), that are collecting data may have a meeting location or number associated with the client devices as to reflect that they are associated with the singular meeting. In another example, the multiple client devices may include in the data that is sent to meeting program 120 a reference or title stating that the collected data is related to the singular meeting or any other method that is that is known by a person skilled in the art. In another embodiment, meeting program 120 receives data from multiple client devices collecting data from multiple meetings. In various embodiments, the meeting may take place in a conference room, on a phone, via video chat, or any other method known by one skilled in the art.

Meeting program 120 identifies one or more original topics in the data (step 204). In an embodiment in which audio data is received by meeting program 120, audio data is converted to text to aid in identifying an original topic. In an example, meeting program 120 receives a live audio feed from client device 104 and converts the audio data to text using hidden Markov models, dynamic time warping, latent Dirichlet allocation (LDA), or any other method known by a person skilled in the art. In another embodiment, meeting program 120 identifies an original topic that has been or is being discussed in a meeting. For the purposes of this application, original topic is any topic being discussed in a meeting and the data relating to that meeting is sent to meeting program 120 by software collecting the data on client device 104. In one example, meeting program 120 continuously reviews the new data that is being received in real time to identify an original topic being discussed. In this example, meeting program 120 utilizes LDA to identify the original topic being discussed. In another example meeting program 120 may identify the original topic based on each word that is used to identify the original topic of discussion (e.g., meeting program 120 would identify an original topic of “cat” when words such as kitten, whiskers, milk, hair, claws, and tail are used within a short amount of time, such as 1 minute.) Meeting program 120 may also identify the original topic of discussion from audio data converted into text by searching for key words, the number of words used, latent semantic analysis (LSA), and/or, in documents or pictures with picture recognition, and/or graphical text analysis, or any other method known by a person skilled in the art.

In one embodiment, meeting program 120 may track the evolution of the topic during a meeting as it evolves from one topic to the next. In an example, meeting program 120 may plot the topic on a multidimensional space and track the topic which has an evolving present end and a dispersing past end. The plot may resemble a comet, which has a wide tail, or passed points on the plot because the topic was discussed in broad terms; however, the most current point may be small as only one small bit of information pertaining to the topic has been discussed, such as in FIG. 3. In another example, the plotted points may depict a broad line for broad discussions of a topic and a narrow line for narrowing discussions of a topic. By plotting the topic, meeting program 120 may be able to make future predictions on how the topic is trending and make a prediction on what the topic may be at a future time as well as the future productive use and understanding of the topic by the participants. In another example, meeting program 120 may be able to determine if a meeting is going to conclude in the near future by analyzing previously received data, such as speech activity, measure of focus, content independent analysis, content interdependent analysis, physiological measure, and/or plotting of the trend of the original topic.

Meeting program 120 assigns a value to an original topic based on participants productive use and understanding of the original topic (step 206). In one embodiment, meeting program 120 assigns a value to represent the productive use and understanding by the participants of the meeting of the identified original topic based on the data previously collected by client device 104. In an example, the assigned value is a numerical value which has a positive sign for productive use and understanding of the topic and negative sign for less productive use and understanding of the topic. In an example, meeting program 120 uses a variety of methods independently or in conjunction to determine a value to represent the productive use and understanding comprising network analysis of text, focus of attention of meeting participants, mood analysis, total activity levels, the participant's physiological measures to an analysis of meeting dynamics across different predetermined dimensions, or any other methods known by someone skilled in the art. In another example, meeting program 120 determines the productive use and understanding of the topic by receiving data regarding polling information from participants of the meeting from client device 104, or another client device (not depicted). Examples of dimensions may comprise meeting directedness, cohesiveness, constructive discussion, urgency, etc. Meeting program 120 analyzes the data collected during the meeting from software located on client devices, such as client device 104, and based on the predetermined dimensions assigns a value for the understanding of the topic. For example, if the participants of the meeting are shifting in their seats, seem sluggish, yawning, etc., meeting program 120 may assign a negative value to represent less productive use and understanding of the topic. In another example, meeting program 120 may assign a negative productive use and understanding value if the participants of a meeting are debating a topic or volume of voices are raised. In another embodiment, the value for the original topic may continually evolve based upon the participants' productive use and understanding of the topic being discussed and the evolution of the topic itself.

Meeting program 120 determines whether data indicates a similar topic exists on a second client device (decision 208). In an embodiment, meeting program 120 compares data from a second client device to a first client device to determine if data received from a second client device (e.g., client device 106) indicates a topic is similar to the original topic. In an example, meeting program 120 identifies multiple topics occurring simultaneously in multiple separate but concurrent meetings, data from which are being received from multiple client devices (not depicted) by meeting program 120. In this example, meeting program 120 measures the distance between the topics in the separate but concurrent meetings to determine how similar the topics are to the original topic. Meeting program 120 determines the distance by using LDA, network analysis of text, image similarity detections, or any other method known by a person skilled in the art.

In another embodiment, meeting program 120 may determine if a similar topic was previously discussed in a meeting that is currently ongoing or that has already ended. In yet another embodiment, meeting program 120 may determine if an individual or group has a particular expertise in the original topic. In an example, where the original topic pertains to ship building, meeting program 120 may search a company database to determine if any personnel have listed a specialty in ship building or have published papers related to ship building, seaworthiness, etc.

If meeting program 120 determines that the data indicates that a similar topic does not exist on a second client device (no branch, decision 208), processing for program 200 completes. In an embodiment, data from the second client device is received similarly to how data is received in step 202. In an embodiment, if the original topic is not within a preset distance to the similar topic then meeting program 120 would go to end. In one embodiment, meeting program 120 does not have a preset threshold, but rather the assigned value of productive use and understanding of the topic from step 208 determines the distance needed to reach the threshold.

If meeting program 120 determines that the data indicates that a similar topic does exist on a second client device (yes branch, decision 208), processing continues to decision 210. In an embodiment, the original topic is within a threshold distance to a similar topic. For example, data received from client device 106 indicates that the topic being discussed is similar to data regarding a topic from client device 104. In this example, the distance between the two depicted topic points on a graph are within a threshold distance.

Meeting program 120 determines if a threshold is exceeded based on assigned value and distance for similar topics (decision 210). In an embodiment, meeting program 120 determines if the difference between the assigned value of the original topic from client device 104 and the assigned value for the similar topic from client device 106 meet or exceed a threshold. In an example, the data containing the original topic received from client device 104 has a −1 assigned value, and the data containing the similar topic received from client device 106 has a +2 assigned value. The determined similarity distance between the topics for the original topic and the similar topic is measured at 1. In this example, the threshold for the assigned value and distance is not exceeded, and the program goes to end (no branch, decision 210). In various embodiments, a variety of thresholds can be set. In one example, a threshold may be set based on a difference of 1 for an assigned value as long as the distance is under 0.5. In another example, there may be a ratio between the distance and the assigned value. If a value of −5 correlates to a meeting which is totally dysfunctional and the participants of the meeting lacking productive use and understanding of the topic, then the allowed distance value may be increased to allow for meeting program 120 to find a meeting in which the participants have a good productive use and understanding of a similar topic and may be of some help.

In one embodiment, meeting program 120 may also utilize information related to if a discussion of a topic has just begun, or the entire meeting is about to conclude. In an example, meeting program 120 may not conclude a topic that has exceeded the threshold if the meeting is about to adjourn or change topics. In various examples, meeting program 120 estimate that a meeting is about to conclude, or change topics. In another example, meeting program 120 determines that the threshold has been exceeded based on the assigned value and the distance for similar topic which triggers an action (yes branch, decision 210).

Meeting program 120 sends an indication to a client device (step 212). In an embodiment, when a threshold has been exceeded, such as yes branch, decision 210, an action is triggered which sends an indication to a client device. In an embodiment, meeting program 120 has previously determined that a threshold has been exceeded for an assigned value and the distance between the original topic and a similar topic for the meetings taking place on client device 104 and client device 106. In an example, the topic being discussed in the meeting for client device 104 has a high value assigned for productive use and understanding by the participants, and the meeting for client device 106 has a low value assigned for productive use and understanding by the participants. In this example, meeting program 120 may send an indication to client device 106, showing a display or some other form of notification that indicates another meeting is currently taking place in which the same topic is being discussed with a great productive use and understanding of the topic. In another example, the indication may first be sent to the client device which has the higher productive use and understanding of the topic being discussed to allow the members of the meeting to make themselves available to provide help on the topic.

In one embodiment, multiple available notifications may be displayed indicating the proposed helpfulness to the ongoing meeting. For example, three notifications may pop up on a screen indicating that three meetings are discussing the same topic. The notification may indicate a degree in which meeting program 120 rates that the meeting with the similar topic based on distance of topics and assigned values of productive use and understanding, such as numerically (e.g., 100%, 85%, 50%), color coordinated (green, yellow, red), etc. In an example, the notification may also include information such as the meeting location, the time and date the meeting took place, if it is not a live meeting, meeting participants, etc. In another example, the notification may include the ability to pause or rewind a feed, comment, store information, etc.

In one embodiment, the notification may appear blank, but as the topics become more similar, and/or the participant's productive use and understanding of the topic becomes more distant, a tunnel and/or linkage may appear, allowing participants of the notified meetings to have accesses to each other's meetings. In various examples, there may be a variety of security protocols or allowance to allow for the tunnel and/or linkage to form. In various embodiments, the notification tunnel and/or linkage may be in virtual world meetings and/or real world meetings, and the tunnel and/or linkage may allow for control of the flow of dialog, such as audio only, video only, both, avatar leap from virtual world onto the screen of a videoconference outside the virtual world, video display within the virtual world, etc.

In another embodiment, meeting program 120 may send an indication regarding a particular individual that might be helpful to the meeting based upon similar topics. In an example, meeting program 120 may determine, based on the assigned value of the original topic, that it is best to crowd source the topic to individuals that have relevant information to provide to the meetings. The crowd sourcing could be individuals, group meetings, company-wide, community-wide, country-wide, world-wide, etc.

FIG. 3 is a graphical representation of two simultaneous data streams and the possible convergence on a similar topic during simultaneous meetings, in accordance with an embodiment of the present invention. In one embodiment, meeting program 120 plots two topics as the two topics evolve during concurrent meetings sending data from client devices 104 and 106 to server 102 via network 108.

In depicted graphical representation 300, data stream 302, which is received from client device 104, and data stream 304, which is received from client device 106 are graphical representations of topics being discussed in separate meetings both of which are sending data to server 102. In this embodiment, meeting program 120 plots the evolution or progression of the topic over time as well as assigning an evolving value based on the productive use and understanding of the topic by the participants of the meeting. Data stream 302 and data stream 304 are about to converge on the same topic, and data stream 302 has a negative assigned value and data stream 304 has a positive assigned value. In an example of the represented merger, the meetings may receive an indication prior to the actual convergence of the topic, and as the topics get closer to converging as well as the assigned values increase in opposition, the identification may change to reflect the helpfulness of linking the meetings.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Referring now to FIG. 4, a schematic of an example of a cloud computing node is shown. Cloud computing node 410 is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, cloud computing node 410 is capable of being implemented and/or performing any of the functionality set forth hereinabove.

In cloud computing node 410 there is a computer system/server 412, which is operational with numerous other general purpose or special purpose computing system environments or configurations.
